Which of the following planets has very little atmosphere?

Mars, has a thin atmosphere composed of about 95 percent carbon dioxide

Explanation:The leading theory is that Mars' light gravity, coupled with its lack of global magnetic field, left the atmosphere vulnerable to pressure from the solar wind, the constant stream of particles coming from the sun.

Explanation:

Mercury’s atmosphere containing oxygen (42%), sodium (29%), hydrogen (22%), helium

(6%), potassium (0.5%) and water vapor.

2. Venus

The atmosphere of Venus is one of the most chemically complex and dynamically active

planetary atmosphere in the solar system. The Venusian atmosphere consist of carbon

dioxide (95.5%), nitrogen (3.5%), sulfur dioxide (0.015%), argon (0.007%), carbon monoxide

(0.002%), helium (0.001%), neon (0.001%).

3. The Earth

The atmosphere of Earth is mainly composed of nitrogen (78.08%) and oxygen (20.95%).

The remaining part of the atmosphere divided into the permanent and the variable

constituents. The permanent constituents consist of the five noble gases, argon, neon,

helium, krypton and xenon also other materials such as carbon dioxide, hydrogen, methane,

nitrous oxide and radon. The variable constituents of the atmosphere are water, carbon

monoxide and ozone.
